| 摘 要： | 3GPP在R5核心网引入了IMS结构，并选择会话初始协议（SIP）作为呼叫/会话的控制信令。但在无线环境下消息过长成为SIP在IMS中的应用瓶颈。在SigComp框架下，对各种压缩算法进行了比较，并根据SIP消息特点选择LZSS算法作为SIP信令压缩的基本算法。为了进一步提高SIP信令的压缩比，提出了LZSS＋Huffman的压缩算法及其实现流程，并对算法的压缩效果进行了仿真分析。

| Abstract: | IMS was introduced into R5 core network by 3GPP, and 3GPP chose Session Initiation Protocol (SIP) as the call/session control Signa1ing. However, under the wireless circumstances, large SIP message becomes a bottleneck when SIP is used in IMS. Based on the SigComp, this paper compared various compression algorithms and chose LZSS as the basic algorithm to compress SIP according to the characteristics of messages. To further improve the compression ratio, the authors brought forward a new algorithm based on LZSS and Huffman combination and make simulation analysis of the results of several compression algorithms. |
